Manufacturing Quality Control of 11-MERCAPTOUNDECANOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized KOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Thiol Content | Iodometric Titration | Oxidation of free -SH groups by excess iodine, followed by back-titration of unreacted iodine with sodium thiosulfate. |
| Water Content | Karl Fischer Titration | Electrochemical determination of water via reaction with iodine, sulfur dioxide, and base in methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750 C in a platinum crucible, then weighing inorganic residue after complete combustion of organic matter. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measurement of metal ion concentration after acid digestion and matrix matching. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation and quantification of sulfate anion using suppressed conductivity detection after alkaline eluent separation. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index by comparison to APHA color standards or absorbance at 430 nm in dilute solution. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary tube apparatus with controlled heating rate. |
| Residual Solvents (e.g., Ethanol, THF) | GC-FID | Gas chromatographic separation followed by flame ionization detection, quantified against internal standard calibration. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 589 nm using a sodium lamp, corrected for concentration and path length. |
